We love Google Easter Eggs, and this one is even better than any of last week's new YouTube offerings: an option that lets you explore the inside of the TARDIS console room via Street View. Yep, it turns out even Google Maps is bigger on the inside.
To check out the TARDIS, visit this link and either click on the double-arrow you see near the bottom of the screen or press the Up key on your keyboard. (The latter works better if you're in the new Google Maps interface).
Sadly, you don't seem able to activate the TARDIS using standard Google keyboard shortcuts (we'd suggest j to go back an hour, k to move forward).
